The discovery of natural gas in 1959 nearby Groningen paved the road for the development of the gas transmission grid in the Netherlands. Gasunie Transport Services (GTS) owns and manages the grid. GTS provides shippers commercial services like the facilitation of gas trade on TTF (Title Transfer Facility) and TTF-B (Balance Agreement). TTF is an important gas hub and is even linked with the United Kingdom via the BBL pipeline. The Balance Agreement provides a shipper the possibility to transfer (a part of) the imbalance risk to another shipper. TTF-B is available for shippers transporting gas to domestic physical network points. Delivering to domestic end users requires flexibility and gas storages like Bergermeer (TAQA) and Zuidwending (EnergyStock) can offer the flexibility needed.

The power transmission grid is maintained and operated by TenneT. The high-voltage grid is connecting electricity producers to consumers, and connects and integrates electricity markets in Northwestern Europe. TenneT ensures that supply and demand are in balance using the 50 Hz balance frequency as input for corrective actions. Balance Responsible Parties (Dutch: Programmaverantwoordelijken) need to specify how much they expect to feed into and take out of the grid each day. Based on the programmes TenneT calculates and deploys reserve and emergency power for balancing the grid. Imbalances of the Balance Responsible Parties are offset according the imbalance pricing system.
